As part of the device tree stuff, some things are basically children of FIQ. Allow
a callback in the machine-specific code to attach the children when the FIQ device has
been instantiated

FIQ is back up again, changed the stack to point to the post FIQ-vector
area, remove various meddlings needed to try to fix it.

On GTA02 we use FIQ to manage the vibrator IO now. That
is necessary because we stole timer3 from doing hw pwm
for vibrator. This keeps the same UI in /sys but does
"bitbang pwm" on the same vibrator GPIO

This makes the FIQ stuff specific to one of the timers on the
s3c244x and adds the platform stuff for fiq in the gta02 init
Currently one sysfs node is exposed, a count of FIQ events

Adds a C-based FIQ ISR which is very convenient (and unusual --
normally you have to do FIQ ISR in assembler only).
Based on my article:
http://warmcat.com/_wp/2007/09/17/at91rm9200-fiq-faq-and-simple-example-code-patch/
Implemented as a platform device and driver.
Suspend / resume is tested and works.
